The synthetic graphite manufacturing process consists of the following principal stages:
Powder preparation
Shape forming
Baking
Graphitization
Pyrolytic graphite
Powder Preparation
Raw materials for synthetic graphite fabrication (petroleum coke, pitch coke, carbon black, natural graphite and secondary graphite scrap) are loaded and stored in raw materials silos. At the first step, the raw materials are pulverized (ground) in crushers and ball mills. The resulting powder is conditioned according to the particle size distribution (screening). The final step of powder preparation process is blending the powder with a binder. Coal tar pitch, petroleum pitch or synthetic resins are used as binders.
